Jeopardy! to air final episode hosted by Alex Trebek tonight

Tonight is the end of an era for Jeopardy! fans. It's the final episode hosted by Alex Trebek. 
The show does not feature a farewell from the beloved host because Trebek didn't plan for it to be his last episode.
It was filmed about 10 days before Trebek died in November after a battle with pancreatic cancer.
The episode will feature a tribute package celebrating Trebek's legacy.
